PPT-Forces and Fluids

Chapter 12 BIG IDEAS Newtons laws apply to all forces Gravity is a force exerted by all masses Friction is a force that opposes motion Pressure depends on force and area Fluids exert a force on objects. Now we are the first to take it out In 2001 Baroid introduced its ACCOLADE57518 system bringing a new generation in drilling fluid technology to the industry The ACCOLADE fluid is the industrys first clay free highperformance invert emulsion fluid A The Grand Challenges in Quantum Fluids and Solids. The Grand Challenges in Quantum Fluids and Solids. The Grand Challenges in Quantum Fluids and Solids. Or. We’ve been through all this in Europe already. Classification of Non-Newtonian Fluids. Laminar Flow of a Non-Newtonian fluid in Circular Pipes. Recommended text-book: W.F. Hughes, J.A. Brighton, . Schaum's. outline of theory and problems of fluid dynamics, New York: McGraw Hill, 1999. NON NEWTONIAN FLUIDS du Fluids. A fluid is anything that flows: liquids and gases. One . common characteristic is that fluids have no fixed shape and are easily . deformed: . t. ake the shape of their containers.. Density. The density of a substance is the quantity of matter contained in a unit volume of the substance. . Dr . Pankaj. Sharma . MD(Pediatrics). HOW . TO GIVE ?. HOW MUCH TO . GIVE ?. WHAT TO GIVE?. HOW TO GIVE. Electronic Devises.. . Infusion Sets. Pediatric drip set. Pages 66 – 84 in textbook.. A substance that has the capacity to flow and assume the form of the container into which it has been poured.. What is a fluid?. Water, milk, blood and saliva. Gases are also considered fluids: air, helium and ozone.. 11.2 . Floating and Sinking. Buoyancy= the ability to float. buoyant force . – acts in a direction opposite gravity so it makes an object feel lighter. . O. k. . Let’s make sure we understand what is going on. . pg . 390-404. Today’s Learning Objectives:. Know the terms in this chapter.. Be able to solve word problems involving pressure.. What is the relationship between pressure and depth of fluid?. Fluid Pressure (Sec 13-1) . What is pressure?. Pressure is the force per unit area that is applied on the surface of an object.. Chapter 12: Forces and Fluids. Calculating pressure. Pressure increases if the force applied increases and decreases if the area of contact increases.. Viscosity is how engineers measure the resistance of fluids when being . deformed:. τ. = . μ. (du/dy. ). The less viscous the fluid, the greater its ease of . movement.. Viscosity is useful for calculating the force needed to move a fluid. For example, in these industries: . Experiment associated with Blaise Pascal. A long thin tube placed into a barrel. Water . is poured in the top that increases the . Hydrostatic Pressure based on elevation. and causes the barrel to burst. . Both gases and liquids are . fluids. Fluids have:. No fixed shape. Flow easily. Deform under an applied force. In fluids on the molecular level:. Molecules are in constant motion. The velocity of the molecules depends on the temperature. The Covenant sets out the relationship between the nation, the government and the Armed Forces. It recognises that the whole nation has a moral obligation to members of the Armed Forces and their families, and it establishes how they should expect to be treated. .
